Ummm sm GRAVEL LOADER.

Application filed' December To all whom it mmyconce/m.'

Be it known that I, HOWARIYE Sfrrrins, a ,Citizen ot ythe 'United States, residing at Bolivar, in the county y of .Polk and State. of `Missouri,have invented new and useful Improven'ients in'GraVel Loaders, of which the following is a specification.`

The general object ofi this invention isto provide means for faoilitatingthe` loading o'fztruoks, ears` and thelike, witlrgravel and other :materials by -providing an Vinclined track and a car traveling"thereon and rarranged to receive the material atthe'lower part'ot the traok and to'transport it tothe elevated part where it eanbe dumped into the receiving vehiele.

inother object offthe invention is'toprovide means `for automatically'tiltingthe ear Vat theelevated end of the track sothat the material therein `will 'be dumped into "the receiving vehiole wliioh is 'located below the elevat d endl ot the t ack A Aturther object `ot the invention is lo lprovide a single operating cable `torpu'lling the loarup the track, ilor controlling the dumpinglaction auditor returning the parte to their normalposition.

This invention also consists 4in. .certain vother features of eonstructionand in the eon'ibinati'on'and arrangement oii=th`e several parts, to -be hereinafter `:fully described, illustrated in fthe `accompanyingl drawings and specifically pointed 'out'in 'the `appended claims.

In describing my invention in detaihrefference will lbe had to Ithe accompanying drawings wherein like characters denote like or corresponding 4parts throughout the several views,-and in ,whieht- Figure l yis a plan view o'fthelinvention showing the car in load receiving,position. l Figure 9. 4is an elevationshowingthe oar withthe sides raised andreadytobe pulled up the inclined track.

In Athese views 1` indicates a 'framework for supportingthe 'rails' 2 lin an inclined fpo- 'sition A wheeledv iiranieB is adapted to ftravel upon the rails and this fiframe snpports a body 4l. Therear end o'iithis "frame is'provided with an upright piece 5 and the sides G'o-tliehody'are hinged softhatithey ean be swung downwardlytoterm eontinua tions ofthe door onupwardly to yfholdfthe material upon the body. They are held in uiirjight Iposition by means of the hooks ii". l The irontendotthe'car is lett-open. lin- Ielinedplatforms 8 are arranged at the small end oit the irame l, vone at euch side thereof .so that a ear or other Avehiolelean pass ltrom thev ground upon the body when the sides -ot' the'fbody are lowered, so :as ito dump the :loaduponsaid body. "Atter'a loadhas been placed upon *the :body the sides are swungl upwardly and hooked in position.

Theelevated end of the'iframe iis of sutticient height 1toextend wellabove a truek, carer other 'load receiving element lo'oated at theelevated A,eindwof the traek so thatthe load romthe body can Abei dumped into the `said'fvehicle Vfromftheupper end ot thetraek. lrlhe upper` `end otithe track is termed with aidmnping seetion y9, theside bars oi which are madeto embraee the upper ends oi? the railsandliorm eontinnations oi :the ftrfaek. `This `section isjpivotally secured to ythe `high end i ot' the 'frame by uneans oi? i the @rod 10 andithis seetion provided with a eentralbeam ll which extends'downwardly Abelow the endo'f the 'section andisiprovided with a depending part l2 which is adapted lto engage a recessed l.member 13 supported by'the iframe. A pair ot pulleys lfl are lo- -oatedin-themember and apulley l5 isoarriedby the `depending part l2 anda guiding pulley 18 is placed in a recess 1in the bea1n,the pivotio'l which ,is formed by the rod 10. A Cable 1G is passed aronnds id `pulleys and has one end. fastened to .the

wheeled iframe 3 and its other end is adapt-` `ed tobe tastened Vteeny powerappliance or a team so as to pull the wheeled frame and body up the track. Stops 17 are arranged on the dumping section for engaging the front wheels of the wheeled frame to prevent further movement of said frame.

After the load has been placed upon the body the sides thereof are swung upwardly and hooked in position. The cable is then pulled upon so as to pull the wheeled frame and its body up the track. lVhen the 'front `wheels strike the stops 17 Yfurther movement of the wheeled frame will be prevented and the weight of the parts and load will cause the pivoted section ot the track to tilt and thus discharge the load into the wagon or other vehicle which has been positioned at the high end of the frame. After the load has been discharged the cable is pulled upon so asto lower the pivoted section and the car by means of the cable engaging the pulley on the depending part; 12. lVhen the pivoted section is in lowered position the cable is slackened so as to permit the car to run down the track to its starting point.

As will be seen when the parts are in dumping position the cable is looped around pulley 15 on the depending part 12 so that ,when a pull is exerted upon the cable this loop will pull the depending part downwardly into the recessed member and then the pulleys 14 and 15 are adjacent each other.

In order to prevent 'the car Jfrom running away if the cable should break or some other part give away I provide an automatic holdfing device which consists of a bar 18 having one end pivoted to the frame 3 and having a right angular extending part 19 at its free end which is adapted to engage any one of a series of projections 2() on a rail 2. Thus if the car should start to run do'wn the track fthe part 19 would engage one of the projections and prevent further movement of the car. It' the safety device is not needed it can be renderedv inoperative by means of a slotted link 21 which is pivoted to the bar 1S and which has its slot engaging a bolt 22 on the frame 3. The link has a notch 23 therein which when placed in engagement with the bolt 22 will hold the bar 18 out of engagement withY the projections 20. This safety device must be moved to inoperative position when the car is to descend and this may be done either by hand or by a cam device or projection located adjacent the high end of the track and adapted to strike the bar 1S and raise it to inoperative position when the car reaches this part of the' track.

As will be seen only the one cable is used for drawing up the load,for dumping the load and lowering the car to its position for reloading.

I also provide means for preventing movement of the dumping section of the track as to retract the bolt and said cam is provided with a notch 36 for receiving the lfinger so that the wheel is held against rotary movement as long `as the finger is in the notch. A spring 37 tends to hold the wheel with the flange in inoperative position or in a position where it cannot engage the finger. An arm 38 is connected with the cam wheel and said arm is adapted to be struck by a roller 39, carried by a hanger 40 on the car, as the car moves upwardly over the dumping section of. the track. This movement of the arm will rotate the cam wheel a quarter turn so as to move the cam thereon into engagement with the linger and to place the notch in a position where it will be engaged by the finger. This will hold the bolt n retracted position and the wheel against movement. The dumping section is then free to move into dumping position and as it moves upwardly the Wheel will rise above the finger so as to release the bolt and permit its spring to return it to projected position. The yoke and bolt are provided with beveled portions so that the yoke can pass by the bolt when the dumping section is returned to norma-l position. The arm 38 is so arranged that it will yield to permit the downward travel of the car but it will be pulled back to normal position by the spring 41. The wheel is provided with a slot 42 for receiving a pin 43 so that the rotary movement loi the wheel is limited.

It will thus be seen that the dumping section is locked in normal position until the car starts to travel thereover and then it will be unlocked so that the section and the car can move to dumping position.

It is thought from the foregoing description that the advantages yand novel features of my invention willbe readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

lVhat I claim is 1. A dumping apparatus of the class described comprising an inclined track, a car engaging the same, means at thelower end of the track for vpermitting la load lto be placed upon the car, a dumping section pivotally mounted at the upper end of the track, a guiding pulley at the pivoted point of the section, a depending part at the rear of the section, a recessed member for receiving said depending part, pulleys carried by the recessed member and the depending part7 ya cable passing` around said pulleys and having one end connected with the car and its other end adapted to be pulled upon to draw the car up the t ack.

2. A dumping apparatus of the class de scribed comprising an inclined track, a car adapted to travel up the same, said car having hinged sides,'an inclined runway at each side of the lower end o the t ack with which the said sides will engage when in lowered position to `form a roadway to permit the car to be loaded and means for pulling the far up the track.

3. A loading apparatus of the class described comprising an inclined track, a car engaging the same, means for permitting a load to be placed upon the car at the lower end of the track, dumping means -for the car at the high end of the track, means for drawing the car up the track and for controlling the dumping means7 a spring bolt on the track for engaging a part on the dumping means for holding said means in lowered position, a cam member on the dumping means, a lever connected with the cam member vand a part on the car for striking the lever for causing the cam member to retract the bolt to permit the dumping means to operate, the raising and the dumping means carrying the cam member out of engagement with the bolt.

In testimony whereotl I aliix my signature.
